Default adding tweeters to full range speakers.

this morning when i finished my FR speaker, using the TB 3 inch bamboo driver with a needle enclosure. immediatly, i was unsatisfied with the high's. could i add a tweeter to go from about 18000 hz-25000? I'd prefer not to modify anything with the driver, and just make a crossover for the tweeter. would this be possible?

thanks

Yep. Just find the appropriate value of capacitor to result in a high-pass filter at about 16-18khz, and add a suitably high-frequency tweeter.

It's possible, but I doubt you will hear the difference. Our hearing doesn't go that high. If the speakers sound dead up top, they will be lacking from a much lower frequency.

well thats true how we cant hear that high, but would it be ok for the woofer and tweeter to merge frequencies?

that means i'd set the tweeter to about 13000 hz-above without modifying anything with the driver so both the tweet and woofer do the freq's between 13000 - 20000hz? or wil it sound bad?

Well if its new drivers they certainly deserve a few days to settle and loosen up a bit.

LF,

Try using a small inexpensive tweeter with a 1uf cap.

from my calculations, to acheive a crossover point of 15000 hz in a 1st order system i should use a 1.325 uf capacitor. ill try it out when my tweet comes.

Have fun!

I think you will hear additional treble by adding a super tweeter! I do.
